在全球发展的新时代,人们对于全球治理机制所面对的问题和前景的认识在不断加深,并形成了全球发展的理念及其目标体系。当前,全球治理机制的运作已经逐渐呈现出多元化和多样化的状态。国际组织与当地的民间组织已经通过各种平台紧密地联系在一起。这一机制的演化是从主权国家的援助行动和国际组织协调的模式走向多元组织之间的协调,把国家的政策行为融入到国际治理机制中作为其基本内容的形式。对于普通民众来说,全球社会政策的制定和全球治理体系的运作不再是一个高高在上的东西,而是一个可以渗透到民众日常生活中的活动。 相似文献

The kinetic isotope effect (KIE) was applied in the study of the mechanism of bromine elimination from p-methyl-erythro-a,b-dibromocinnamic acid, successively labeled at the a and b carbons. The large 14C KIE for the b-position and small KIE for the a one of side chain of p-methyl-erythro-a,b-dibromocinamic acid proves that elimination of bromine leading to the formation of (E)-p-methylcinnamic acid proceeds via the E1 mechanism. 相似文献

The original experimental device for studying the radial dependences of emitted radiation, generated by the cylindrically
symmetric positive column of the DC glow discharge, is proposed. Principle of detection of the radial intensity profiles of
the spectral lines by means of the special scanner with two movable conic mirrors is described. The function of the scanner
was verified experimentally and by the method of raytracing. As an example, the radial profiles of lines emitted by the positive
column of the neon glow discharge are presented. No significant changes were found.

Energy spectra have been measured for the (τ, α) reaction at 205 MeV on90Zr, 118,124Sn and 208Pb. Results on the valence neutron shells and on the inner 1f7/2 shell in 90Zr, 1g9/2 subshell in 118,124Sn (T< and T> components) and 1h11/2 subshell in 208Pb are presented. 相似文献

We report the investigation of the Photo-Magneto-Electric effect (PME) in semi-insulating Liquid-Encapsulated (LEC-) grown GaAs crystals, using both intrinsic and impurity excitation. The role of the majority and minority carriers on the conductivity phenomena was evaluated and the lifetimes of electrons and holes were determined depending on excitation conditions. Anomalously high PME voltages, reaching in some cases some volts, were measured, which demonstrate a sharp drop in the temperature region 320–360K. The observed changes are discussed supposing that the influence of the non-homogeneous defect structure of the samples is essential. 相似文献

Both of the title compounds crystallize in the monoclinic system: C23H17NO2 (Ib),P21/c,a = 8.970(1),b = 22.629(5),c = 9.101(1) Å, = 106.08(1) °,Z = 4,D
x
= 1.27 Mg m–3; C19H17NO2 (Ic),P21/a,a = 15.225(2),b = 6.429(1),c = 17.190(1) Å, = 112.99(1) °,Z = 4,D
x
= 1.25 Mg m–3. The structures were solved and refined by standard methods, both toR 0.04. In compound Ib, a weak intramolecular interaction is observed between the nitrogen atom from the isoquinoline ring and the carbon atom from the carbonyl group, with the N(2) . C(18)distance being 2.98 Å. In compound Ic, the PhCO2 -fragment is twisted in the opposite direction to that in compound Ib, without hydrogen bonding. The pK
a
and IR data were considered in the light of the results of the X-ray investigation. 相似文献
